The 100 service manual is not approved data for major repairs, a 337 with the repair described in block 8 and a FAA approval stamp in block 4 would be required. Am I correct in my appraisal of the CFR's? From my further reading of the CFRs this is a major repair and requires an inspection by the IA before sign-off.

After reading the CFR's I am reasonably sure that the service manual is approved data. The stringers had to be cut and repaired according to the Cessna 100 series service manual. All new parts were used such as ribs and skins. Ron Fenili wrote:My A&P is nearly finished with repairing the outer two ribs on the wings of my 170b.
